Fabric to attach to the wall
1 can of spray starch or liquid starch
1 sponge, or I used a facewasher
Start by cutting the shapes you plan on attaching to the wall, I didn't bother edging them, once attached they don't seem to be prone to fraying.
Next make sure the wall is clean and dry, and the process for attaching them is really easy, first spray the starch on the wall, so it is damp.
Next place your fabric on the wall and smooth out, make sure it is all saturated. Remove any air bubbles it may have, though as it dry's I found a few returned.
Finally use the cloth or sponge to dab up any excess starch.
Once finished run your cloth or sponge under some water and clean up any starch marks. They dried in about 3 hours and they also just pull off.
